Most won't set foot near the index futures overnight, they have been brain washed to closing out all positions and being flat over night. Brokers love these guys because it keeps the commissions coming.

I have never seen anyone mention an actual strategy for this type of trading. This truly is easy money. Buy the cash close and wake up and smell the profits.

Last night I was watching the futures closely and noticed as soon as the electronic exchanges for stocks close in the evening @ 7:00pm cst, The futures started rising.
